NCP5387

2/3/4 Phase Controller for

CPU Applications

The NCP5387 is a two−, three−, or four−phase buck controller

which combines differential voltage and current sensing, and

adaptive voltage positioning to power both AMD and Intel

processors. Dual−edge pulse−width modulation (PWM) combined

with inductor current sensing reduces system cost by providing the

fastest initial response to transient load events. Dual−edge

multi−phase modulation reduces total bulk and ceramic output

capacitance required to satisfy transient load−line regulation.

A high performance operational error amplifier is provided, which

allows easy compensation of the system. The proprietary method of

Dynamic Reference Injection (Patented) makes the error amplifier

compensation virtually independent of the system response to VID

changes, eliminating tradeoffs between overshoot and dynamic VID

performance.
